Abstract

A scraper for removing material, adhered to a surface, in strips. The scraper has a front scraping edge and at least one cutting edge at one end of the scraping edge. The cutting edge extends generally transverse to the scraping edge.

Claims

1. A scraper comprising:

a scraping blade having a front scraping edge;

a handle connected to the scraping blade, said handle extending rearwardly of said scraping blade;

at least one cutting blade having a front cutting edge; and

means for mounting said at least one cutting blade on one side of the scraping blade with the cutting edge of said cutting blade extending generally transverse to said front scraping edge,

wherein said mounting means are of the detachable type and comprise for each of said at least one cutting blade;

a dihedral mounting brace having one arm detachably connected to the scraping blade and another arm extending perpendicular to the one arm, said other arm being provided with a central threaded hole;

a C-shaped mounting plate sized to fit over the other arm of the brace, said mounting plate having a central trough hole aligned with the threaded hole of the brace; and

a locking screw passing through said through hole and engaging said threaded hole for tightening the mounting plate to the mounting brace with the cutting blade sandwiched therebetween.

2. A scraper as claimed in claim 1 wherein:

the one arm of the mounting brace comprises a downwardly projecting hook for use to connect it to the scraping blade, said hook engaging a hole provided in said scraping blade; and

said C-shaped mounting plate comprises a vertical wall and a pair of small upper and lower projecting flanges vertically spaced apart to such an extent as to snugly extend above the other arm of the brace and under the scraping blade, respectively.

3. A scraper as claimed in claim 2, comprising two cutting blades mounted on the one and the other sides of said scraping blade, respectively.

4. A scraper as claimed in claim 3, wherein the cutting edge of each cutting blade is generally adjacent the front cutting edge.

5. A scraper as claimed in claim 4, wherein the front scraping edge is detachably mounted on the scraping blade and wherein said scraper further comprises:

a stop bead upwardly projecting from the scraping blade to prevent the scraping edge from moving rearwardly; and

a wedge-shaped cap screwed on top of the scraping blade to hold the front scraping edge in position.

6. A scraper as claimed in claim 2, wherein the front scraping edge is detachably mounted on the scraping blade and wherein said scraper further comprises:

a stop bead upwardly projecting from the scraping blade to prevent the scraping edge from moving rearwardly; and

a wedge-shaped cap screwed on top of the scraping blade to hold the front scraping edge in position.

7. A scraper comprising:

a scraping blade having a front scraping edge;

a handle connected to the scraping blade, said handle extending rearwardly of said scraping blade;

at least one cutting blade having a front cutting edge; and

means for mounting said at least one cutting blade on one side of the scraping blade with the cutting edge of said cutting blade extending generally transverse to said front scraping edge,

wherein the front scraping edge is detachably mounted on the scraping blade and wherein said scraper further comprises;

a stop bead upwardly projecting from the scraping blade to prevent the scraping edge from moving rearwardly; and

a wedge-shaped cap screwed on top of the scraping blade to hold the front scraping edge in position.

8. A scraper comprising:

a scraping blade having a front scraping edge;

a handle connected to the scraping blade, said handle extending rearwardly of said scraping blade;

a blade mounting member supporting the rearwardly extending handle;

means for mounting the scraping blade onto said mounting member with the front scraping edge of said scraping blade projecting forwardly of said mounting member;

at least one cutting blade having a front cutting edge; and

means for mounting said at least one cutting blade on one side of the scraping blade with the cutting edge of said cutting blade extending generally transverse to said front scraping edge;

wherein said means for mounting said at least one cutting blade comprise a mounting plate with a central hole and a screw for fixing said mounting plate to one lateral side of the blade mounting member with the cutting blade sandwiched therebetween.

9. A scraper as claimed in claim 8, comprising two cutting blades mounted on the one and the other sides of said scraping blade, respectively.

10. A scraper as claimed in claim 9, wherein the cutting edge of each cutting blade is generally adjacent the front cutting edge.

11. A scraper as claimed in claim 10, wherein said cutting blade is perforated to let the fixation screw of the mounting means pass therethrough.
